Quick answer — the Oresund Strait now

Ship transits through the Oresund Strait were within its usual range in the 7 days to 18 Oct 2026. The measurement is updated weekly, so it shows a change 4 to 11 days after it happens, and it does not say whether the strait is open or closed. 1 event was linked to the Oresund Strait in the last 30 days. 0 of them name the Oresund Strait in the reporting; the rest were only placed nearby.

The 7-day average of ships passing the Oresund Strait is compared with the same average over the 12 weeks before. It is outside its usual range only when it is statistically unusual against those weeks and at least 15% away. The full rule, and what a record does and does not state, are on Transit Anomalies.

Frequently Asked Questions

Is the Oresund Strait open or closed?▼
This page does not say. What it can state is whether the number of ships passing the Oresund Strait is at its usual level, from a weekly-updated measurement, and which events reporting has linked to it. A fall in transits can come from a closure, an attack, weather, holidays or re-routing, and the measurement does not say which. Check the reported events and their sources for the reason.
Can I see live satellite images of the Oresund Strait?▼
No free source shows a strait live at a useful resolution. Free Sentinel-1 radar and Sentinel-2 optical imagery pass over a place every few days; radar works through cloud and at night. Satellite pass prediction works out when a satellite can next image the Oresund Strait, and the Sentinel-1 viewer shows the most recent free radar pass.
How is “usual” ship traffic decided?▼
Usual level: the median of the 7-day averages over the 12 weeks before. A 7-day average is outside its usual range when it is statistically unusual against those weeks (modified Z-score of 3.5 or more) and at least 15% away. Only container, dry bulk, general cargo, ro-ro and tanker ships that broadcast AIS are counted. The measurement is updated weekly, so a change shows 4 to 11 days after it happens.
What does “named as the location” or “nearby” mean on an event?▼
How the event was linked to the Oresund Strait. “Named as the location” and “named as the target” mean the reporting named this place as where something happened or what was struck. “Named as the subject” means the reporting was about it but did not describe a physical event there — a statement, a market move or an explainer. “Nearby” means only that the event was placed close to it — an association, not a statement that it happened here.
